ORE CONCENTRATOR.

Application filed November 26, 1923.

To @ZZ whom t may concern:

Be it known that we, CLAUDE N. BinLnN- enne and ALBERT E. RoersoN,citizens of the United States, residing at Deer Lodge, in the county ofPowell and State of Montana, have invented certain new and usefulimprovements in Ore Concentrators, of which the following is aspecification.

This invention relates to ore concentrators of that type wherein theseparation of the values or heavier metal particles and the gangue orlighter constituents from the ore is effected by the combined action ofa washing` operation and an agitating operation.

The primary object of the invention is to `generally simplify andimprove ore concentrators of the above kind whereby the same will berendered extremely effective in operation and will be simple and durablein construction. f

Another object ofthe invention is to provide an ore concentratorembodying an elongated shaking box or table in the general form of atrough provided with baffling plates, and means for adjusting thedistance between said plates and the bottom of the box or table wherebythe box may be ef` fectively operated in connection with ore of varyingcoarseness.

Still another object of the invention is to provide the adjustableslides with horizontal baffling boards whereby maintenance of theheavier metal particles at the bottom of the box or table will beinsured, provision being made by a peculiar construction of the sides ofthe box for facilitating the flow of the gangue over the sides of thebox to a desired point of disposal.

Still another object of the invention is to provide a novel and improvedarrangement of washing means whereby the ore will be subjected to jetsof water in the shaking table or box for effectively breaking up anddissolving the ore constituents, so that the values will readilyseparate therefrom.

Other objects will appear as the nature of the invention is betterunderstood, and the same consists in the novel form, combination, andarrangement of parts hereinafter more fullydescribed, shown in theaccompanying drawing and claimed.

In the drawings wherein like reference characters indicate correspondingparts throughout the several views:

Figure 1 is a top plan view of an ore Serial No. 677,087.

concentrator constructed in accordance with the present invention.

Figure 2 is a longitudinal sectional view thereof, taken substantiallyupon the line 2 2 of Figure l.

'Figure 3 is an enlarged transverse sectional view, taken upon the line3 3 of Figure l, and

Figure 4 is an elevational view of one of the baffling slides and itsattached horizontal baiiiingplate or board.

Referring more in detail to the drawings, the present invention consistsof an elongated open top box including side walls 5 having longitudinalgrooves in the inner faces thereof adjacent their lower edges7 in whichthe opposite longitudinal edges of a bottom wall 6 snugly fit, and thewalls 7 and 8 being provided between the side walls 5 with their sideedges disposed in vertical grooves in the adjacent faces of the walls 5as shown clearly in Figure l, the end walls 7 and 8 being provided withgrooves in the inner faces thereof, near their lower ends in which theends of the bottom walls k6 are seated, and tie bolts 9 being providedbetween the projecting ends of the side walls 5 outwardly of the endwalls 7 and 8 for securing the several walls of the box constructionrigidlyl assembled.

The box thus constructed is gradually reduced in depth from its intakeend at the end walls 7 to its discharge end at the end wall 8, byproviding inclined upper edges on the side walls 5 and forming the endwall 8 of shorter size than the end wall 7. The box also tapers narrowerin width toward its outlet end by providing converging side edges on thebottom wall 6 as shown clearly in Figure l, and the interior of this boxis divided into a plurality of successively smaller compartments bymeans of a plurality of vertical substantially uniformly spaced slides10 whereby compartments are provided which vary in size according to thesizes of the values concentrated or collected inthe bottoms of saidcompartments.

The side walls 5 are provided with aligned u and the lower edges of eachof said slides.

In thev construct-ion shown, each slide 10 is provided With aninternally threaded boss 12, at each side of the same and at the upperend thereof, through which the screws 11 are threaded, and whereby thesaid screws are positioned to bear upon the upper edges of the sideWalls for effecting the above mentioned adjustment. n

Suitably rigidly secured to the lower end of the slide are horizontalbattling boards 12 that project toward the outlet end of the bex andwhich act to keep the metallic particles in the box. In order tofacilitate flow of the gangue over the sides of the box, behind each ofthe'slides 10, the upper edges of the` side walls 5 are notched or cutaway at diametrically opposed points as indicated at 13.v Y

The ore washing device of the construetion consists of a pair oflongitudinal nozzle pipes 14 that are seated within grooves provided inthe upper surfaces of the bottom walls 6 and thek side edges thereof andin the inner faces of the side walls 5, said pipes or notches beingprovided with a longitudinal series of openings at 15 upon their innersides and substantially flush with the upper surface of the bottom wall6, so that when water is supplied under pressure Yto the pipes 111-, thesaine will flow inwardly 1n opposite directions and transverselyv of thebox in relatively strong jets, whereby the ore will be effectivelydissolved and washed.

l.with respect to certain constituents thereof,

it being noted that the flow longitudinally of the box is induced, dueto the gradually reduced depth of the same. The ends of the nozzles orpipes 14 may be connected to a common manifold pipe 16 at the intake orhigher end of the box, which manifold is connected with a suitablesupply pipe 1T having a control valve 18. The depth of the pipes 14 atthe shallower or outlet end of the boxY are closed by suitable meanssuch as caps as indicated at 19, .and the table or box4 is adapted to belaterally Yreciprocated or given a jigging movement through the mediumof suitable mechanisms well known in the art. Such means isdiagrammatically shown as consisting of a power shaft 20 having endcranks 21 connected with one of the side walls v5 through the medium oflinks 22. j In operation, the ore is depositedwithin the larger endcompartment of the box at the deeper end of the latter and the valve 18Vis vopened for permitting the water to flow through the openings 15 ina plurality of strong `jets transversely of and across the upper surfaceof the bottom wall (t, it being understoinl that the gates or slidevalrcs 10 have been previously ai'ljusted to the require/e height inaccordance with the, material to be handled. The actimi of the waterimpinging against the ore tends to dissolve the ganglio so that the samemay rise to the top of the water and flow over the top edges of the side*alls particularly at the notches 19, The coarser metal will be retainedwithin the largeiI end comjnirtment and the successive comjmrtments willretain the values in :arcordance with lhe sizes thereof and thedill'erent :n'ljusi'ments` of the several slides 1t). Also, the 'hallingboards 12 while permitting the lighter eonstituents to rise and overllowat the notches 19 will effectively tend to keep the heavier particles ormetals within the box below said notches lf). The concentrated metalsmay be recovered from the several compartments in any preferred or wellhnown manner.

An ore concentrator constructml in aecordance with the above will hefound to operate with extreme ellieieney and may he constructei'l andoperated at a comparatively small cost, and provides a structure whichwill be extremely durable.

llVhat I claim as new is:

1. In an oro concentrator, an elongated box having means forreciprocating the same laterally, said box including side, end andbottom walls, and opposed longitudinal water pipes disposed at thejuncture of the. inner surfaces of the bottom Vall and side walls andhaving longitudinal series of jet openings in the inner sides thereofthrough which water may pass in jets travelling in `wardly toward `eachother across the upper surfaceof said bottom wall.

2. ln an ore concentrator, an elongated box including end, side andbottom walls, the upper edges of said side walls inclining from one endtoward the other whereby the depth of the box is gradually increasedfrom the intake to the outlet ends thereof, vertically adjustable slidesarranged in spaced parallel relation between the side walls andextending transversely of the hox, said side walls having notches in theupper edges thereof at the rear sides ot each of said slides, andhorizontal battling boards rigid with the lower ends of the slides andextending from the latter toward the outlet ends of the box.

In testimony whereof we allix our signatures.
